For the IC buy from a trusted dist. There are many fake semi's out there.
Only other thing I would change is that little diode at the IC. Sry cant
read the C ##.
The 4.7mfd on the 177V is good to change on ANY brand TV. Probably
in the top 10 failures. It can give all sorts of video problems often
subtle.
BTW nice working on it with you. You have a good grasp on things
& you listen ! Wish they all did.
